On Saturday, point guard Avery Vansickle received a pass in transition with nobody in front of her. Instead of laying the ball in, she lofted an underhand pass in the air to Belibi, who was roaring into the lane behind her.

The 6-foot-1 Stanford commit leapt, grabbed the pass with one hand and put down the first alley-oop in girls high school basketball history.

The crowd got loud and, under the basket, the cheerleaders stared in awe. One girl’s mouth fell open as she looked on in disbelief.
